Barium

Barium

Only barium and radium remain.

Barium oxide 2 Iron oxide 1

Radium still refuses to separated from barium.

Barium and radium can not be separated.

Alright, then, radium wouldn't be separated from barium.

The barium meal is a modern derivative of this research.

I drank a barium solution, and stood behind a fluoroscope screen.

This was the problem to separate barium and radium somehow or other.

And though they did not find a way to separate radium and barium in a single process they did discover a method of removing barium little by little in infinite decimal amounts.

All that was now left was to separate these two survivors barium and radium.

Working on the theory that once the whole of the barium is removed nothing could be left but radium.

With the use of barium carbonate as starting material the first commercially used process became available in the 1860s developed by Margueritte and Sourdeval.

And so the work went on until presently everything had been removed from the tons of ore except two final elements one was barium and the other which they had began to think of it in their heart as their own element
